VIBRATING CONCENTRATOR.

Application filed. October 10, 1323. Serial No. 667,652.

To all LU/0m t may concern Be it known that I, lViLLiaM C. CQLEMAN, a. citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Vibrating Concentrators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to ore concentrators the primary object being to provide a novel form of concentrator for separating precious metals from ore pulp'. The invention contemplates a novel form of rotor or drum into which the ore pulp may be fed and in which the concentrates may be separated by centrifugal force without the necessity of employing mercury or amalgamator plates and means is provided for collecting the concentrates while the refuse is passing off through the machine. l

The novel construction of the invention will be apparent by reference to the following description in connection with the accompanying drawings, in which- Fig. 1 is a view partly in elevation and partly in section of a concentrator constructed in accordance with my invention, and

Fig. 2 is a fragmentary sectional view through the drum.

Referring now tothe drawings,

1 designates a bridge tree of an approp-riate frame in which is a bearing 2 receiving a drive shaft 3 rotated by any appropriate means, as for example a pulley t and a belt 5, the belt being driven by any suitable source of power. The drive shaft extends through the bearing 2 and carries on its lower end a drum or rotor 6 which has a lower open restricted end 7 discharging into a hop-per 8 to receive the refuse discharged from the rotor. Adjacent to the restricted end of the rotor are peripheral openings 9 discharging into a receiver or collector 10 adapted to receive the concentrates. lVithin the drum or rotor are a plurality of spirally arranged concentrate receiving ribs or guides 11, the lower ends of which terminate adj acent to the openings 9, the upper ends of which are below a distributor table or disk 12 held in spaced relation with the top 13 of the rotor by the fastening devices which may consist of bolts 14 with spaced sleeves there.- on, the distributor table 'i2 is provided with a central opening 15 through which projects a feed tube 16 having a distributor disk 17 at its upper end overlapping the edges of the opening 15 so that the material discharging on to the disk 17 will flow on to the distributor table 12 and due to centrifugal force when the rotor is rotating the material will be thrown against the wall of the rotor. rherefore the heavier particlesor concentrates will lodge on the spiral ribs and feed down them to the openings 9 through which they will be directed into the receiver or collector 10. In order to assist in the movement of the concentrates down the edges of the ribs or guides, I provide a vibrating mechanism for vibrating the drum or rotor. The means for vibrating the drum or rotor consists of two bands 18 and 19 having cams o-r projections 2O and 21 offset or staggeredwith respect to one another, that is the.. projections or cams 2O will offset with respect to the projections or cams 21 and on the frame 22 is a bracket 23 in which is a pivoted lever 24 having rollers 25 and 26 at its respective ends which constitute hammers to strike against the rotor o-r drum to vibrate the wall thereof.

liVhen the rotor or drum is turning, first one roller and then the other will be struck by one of the cams or projections which in reality constitute tappets and each one of the tappets 21 contacts with a roller 25, the roller 26 becoming a hammer to impart a blow to t-he wall of the rotor, then one of the tappets 21 will contact with the roller 26 so that the roller 25 beco-mes a hammer so that the lever 24E is vibrated against the drum in a. manner well understood by reference to the drawings and this vibratory action against the drum will cause the concentrates to move along, the upper edges of the ribs'to discharge throughthe openings 9 in the periphery of the drum. The refuse pulp passing out through the larger opening surrounded by the constricted portion 7 and then into the hopper where it may be disposed of in any appropriate manner.

vWhat I claim and desire to secure by Letters-Patent is.:

1. A concentrator comprising a vertical rotor, means for receiving ore pulp in the rotor, means for acting on the ore pulp to separate concentrates therefrom, means for discharging the ore pulp, rings about the rotor, tappets on the rings, a vibratory lever having hammers at Vits respective ends, the vibratoryY lever being mounted so that one end will strike against the rotor when the tappet onl onevring engages the other hammer and vice versa 2. A eoneentrator comprising a vertical rotor, means for recei\f'ingrore pulp in the rotor, means for acting on the ore pulp to separate concentrates therefrom, means for discharging the ore pulp tappets on the .rotor arranged in a plurality of cirenlarse-V ries in spaced relation, those of one series Valternating with those in the Votherfand a lever pivoted intermediate its ends for alternately contacting with the tappets to strike against the rotor as the tappets move over the ends of the lever. Y

3. A concentrator cornprisinga vertical rotor, ringsa-bont the rotor, tappets on the ring, a vertical lever pivoted*intermediate itsV ends and hammers on` the respeetiverends of the levers engageable by the tappets whereby the ends o'f'thelever will strike against the rotor when aetuated'by the tappets. Y

In testimony whereof I affix my signature.
